Compositions and methods for treating gonorrhea
The present invention relates to compositions and methods for preventing and/or treating gonorrhea. In particular, the present invention provides compositions comprising an effective amount of a commensal species of Neisseria (e.g., an effective amount of an extract of a commensal species of Neisseria ), wherein such compositions are capable of inhibiting the growth of Neisseria gonorrhoeae.
1. A method for the inhibition of Neisseria gonorrhoeae (Ngo) growth and/or for the killing of Ngo in a product, said method comprising the step of adding to the Ngo a composition comprising an effective amount of a purified genomic DNA of a commensal species of Neisseria selected from the group consisting of Neisseria elongata (Nel) and Neisseria polysaccharea (Npo), wherein the uptake of the genomic DNA by the Ngo inhibits the growth of said Ngo and/or kills said Ngo.
2. The method of claim 1 , wherein said composition is an antibacterial composition selected from the group consisting of a preservative, an antiseptic, a disinfectant, an anti-fouling agent, and a medicament.
3. The method of claim 2 , wherein said antibacterial composition is a preservative in a food product, a feed composition, a beverage, a cosmetic or a pharmaceutical composition.
